IMPROVEMENT IN MACHINES FOR SURFACE-SIZING WADDING, &C.

Specification forming part of Letters `Patent No. 46,065, dated January31, 1865.

To all whom t may concern:

Be it known that I, SAMUEL BAXENDALE, of South Malden, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Machinery for Surface-Sizing l/Vaddin g, Batting, andother Fibrous Fabrics; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in which-Figure 1 is a longitudinal vertical section of a machine with myimprovements. Fig. 2 is a plan of the same.

Similar letters of reference indicate corresponding parts in the severalfigures.

My improvements are more especially designed for the sizing of waddin gor bats made of shoddy, which, owing to its want of tenacity before itis sized, cannot be sized by the apparatus commonly used forcotton-battin g.

It consists principally in the employment for sprinkling the sizing uponthe bat or web of a pin-pointed cylinder, or a cylinder having rigidprojections, operating in combination with a rotary brush, or itsequivalent, from which it receives the size on its pins, and

throwing the sizing upon the bat or web by centrifugal force.

It also consists in a deiiector so applied in combination with theaforesaid cylinder as to deflect a portion of the current ot' airproduced by the rapid revolution of the said cylinder, and therebyconducting a port-ion of it downward into a waste-box, which receivesthe waste-sizing from the said cylinder, and another portion onto thebat or web for the distribution of the sizing on the surface thereof.

lt also consists in the combination, with a device for throwing orsprinkling the sizing upon the bat or web, of a pair of endlesscarrying-aprons made of wire-cloth or other retieulated or perforatedmetallic fabric; and it further consists in the employment within theupper of said aprons of a blast-pipe or blowing apparatus for releasingthe sized bat or web from that apron and causing it' to pass with thelower of said aprons to the dryingroom or to a device which conveys itto said room.

To enable others skilled in the art to make and use my invention, l willproceed to describe it.

A is the framing of the machine, on one end of which is supported thestationary box B,

which contains the sizing, and into which dips the rotatingsupplying-roller O, from the surface of which the sizing is supplied tothe rotati ng brush D, arranged in front of the said roller. Below therotating brush is arranged the pin-pointed cylinder F, which throws thesizing upon the bat or web. This cylinder, the journals of which aresupported in xed bearings, may be made of wood or other suitablematerial, and is studded thickly all over with pins c a of wire of fromabout one-quarter of an inch to three-quarters of an inch in length, andof such thickness that they will not bend in passing through the brushas the cylinder and blush revolve. This cylinder revolves at a highvelocity, so that its pins may throw upon the bat or web by centrifugalforce the sizing which they receive from the brush D as the bat or web,which is represented in red color in Fig. 1, is carried bythelowerendless apron E ot' wirecloth or other reticulated on perforatedmetallic fabric over the large rotating cylinder G, which is arranged insuitable bearings some distance in the front of the cylinder F.

Below the pin-pointed cylinder F there is arranged the waste-box H,which receives the waste-sizin from the said cylinder, and at the frontside of the waste-box there is arranged the detlector I, which consistsof a plate or board of a length equal to that of the said cylinder, andwhich may be adjustable at various angles to deflect into the waste-boxa portion of the current of air produced by the rapid revolution of thesaid cylinder and direct another portion of the said current upon theendless apron E for the distribution upon the web or bat of the sizingsprinkled thereon by the pins a of the cylinder F.

The lower reticnlated or perforated metallic endless apron, E, runs uponthe large rotating cylinder Gr, before mentioned, and upon a rotatingcylinder or roller, J, which may be arranged so that the said apron maydeliver the web or bat into a drying-room, or to another apron whichconveys it to the dryingroom, or be arranged within or beyond the dryirgroom, so that the apron E may carry the bat or web through thedrying-room.

The cylinder G, may be hollow, and have its periphery composed ofwire-cloth or other perforated or reticulated material. The upper apron,Ef, which is made of similar material to the lower one, E, runs upon tworotating cylinders or rollers, K and L, the latter of which is soarranged that the bat or web will be subjected to pressure between thetwo aprons as it passes over the cylinder G, for the purpose ofproducing the adhesion ot' the bers ot' which it is composed by means ofthe sizing which is spinkled upon itby the pins a of the cylinder F. Theupper apron, E', need not be so long as the lower one, E, and thecylinder or roller K is arranged at some distance above the apron E, sothat the two aprons may be separated where the batting is required toleave the upper apron.

M is a blast-pipe, arranged transversely within the upper apron, E', notfar from the cylinder or roller K. This pipe is connected with asuitable blowing apparatus, and has a slit or pert'orations in its underside through which the air is blown through the recticnlations orperforations of the said apron upon the bat or web to detach it from thesaid apron and cause it to follow or be carried by the lower one to thedrying-room. Instead of this pipe M there may be a rotary fan or otherbower a'i'an ged within the apron E.

N is an endless apron, which brings the bat or web from the machinery bywhich it is formed to the endless apron E, which receives it at the backof the cylinder G, and carries it upward past the deector l andpin-pointed cylinder F, to receive the sizing thrown from the points ot'the pins of the said cylinder by centrifugal force. After receiving thesizing,

lwhich is distributed upon it by the portion ot' the current of air fromthe pin-pointed cylinder which passes over the detlector I, the bat orweb is carried under the apron Ef, which compresses it in such manner asto produce the adhesion of its fibers. The aprons E and EQ being made ofa reticulated or perforated metallic fabric, cause the adhesion of thebers to be produced without rendering the web compact, and leave itloose and elastic While giving it a desirable degree of tenacity. Thebat or web after having been compressed between the two aprons E E', isdetached from the upper one, E', by the blast from the pipe M, or itsequivalent, and carried on by the lower apron, E, to the drying room orapparatus.

The cylinder F, instead of having wire pins a on its circumference, mayhave rigid projec tions made of flat plate, or ot' other form.

The sizing may be sprinkled on the endless apron E or cylinder Gpreparatory to their receiving the bat or web, and the bat or web bemade to take the sizing from the apron or cylinder in passing over it.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination of the rotary cylinder F,'having pin-points or otherrigid projections on its periphery, with the rotary brush D, or itsequivalent, from which the pins or projections of the said cylinderreceive the sizing to sprinkle it upon the bat or web by centrifugalforce, substantially as herein specified.

2. The deiiector I, in combination with the cylinder F, substantially asand for the purpose herein described.

3. The reticulatedor perforated metallic endless aprons E E', incombination with a device for sprinkling the sizing upon the bat or web,substantially as and for the purpose herein set forth.

4. The employment, in combination with two perforated or reticulatedendless metallic aprons, E E, operating together as herein described,ot' a blast-pipe, M, or other equivalent device i'or delivering a blastof air applied within one of the said aprons, substantially as and forthe purpose herein set forth.
